In biology, antrum is a general term for a cavity or chamber, which may have specific meaning in reference to certain organs or sites in the body.
In vertebrates, it may refer specifically to:
- Antrum cardiacum, a dilation that occurs in the esophagus near the stomach (forestomach)
- Antrum follicularum, the cavity in the epithelium that envelops the oocyte
- Mastoid antrum, a cavity between the middle ear and temporal bone in the skull
- Pyloric antrum, the initial portion of the pyloric part of the stomach. This is what is usually referred to as "antrum" in stomach-related topics.
- Maxillary antrum or antrum of Highmore, the maxillary sinus, a cavity in the maxilla and the largest of the paranasal sinuses
In invertebrates, it may refer specifically to:
- Antrum of female lepidoptera genitalia

- Simultaneous hepatocyte paraffin-1-positive α-fetoprotein-producing gastric adenocarcinoma and gastric mucosal-associated lymphoid tissue.
- Terada T.AbstractAn 85-year-old Japanese woman was admitted to our hospital because of abdominal fullness. Computed tomography revealed multiple nodules in the liver; the interpretation was metastatic carcinoma. Serum laboratory test revealed extremely elevated α-fetoprotein (AFP) (8820 ng/mL; normal, <10 ng/mL). Upper and lower gastrointestinal endoscopy was performed and identified a large type-2 advanced gastric carcinoma and mucosal irregularity of the antrum. Biopsies were performed. The gastric carcinoma was well-differentiated papillotubular adenocarcinoma. Immunohistochemically, it was positive for pancytokeratins, AFP, hepatocyte paraffin-1 (HepPar1), p53 protein, and Ki-67 antigen (labeling, 70%) but was negative for vimentin, CEA, CA19-9, and lymphoid cell markers. Therefore, the lesion was diagnosed as AFP-producing gastric carcinoma with HepPar1 positivity. The biopsies of the gastric mucosal irregularity revealed severe lymphoid infiltration. The lymphoid cells were centrocyteslike cells with plasma cell differentiation and, immunohistochemically, were composed of CD20-positive B cells. A small number of CD3-positive T cells were also seen. Lymphoepithelial lesions were recognized. Therefore, the lesion was diagnosed as mucosal-associated lymphoid tissue lymphoma. Helicobactor pylori were recognized on Giemsa stain. The present case showed that AFP-producing gastric adenocarcinoma and mucosal-associated lymphoid tissue lymphoma can coexist. They may be associated with H. pylori infection. It was also interesting that the AFP-producing gastric carcinoma expressed HepPar1.

- PURPOSE: There is a growing interest in the use of bedside ultrasonography to assess gastric content and volume. It has been suggested that the gastric antrum in particular can be assessed reliably by sonography. The aim of this observational study was to provide a qualitative description of the son
